AtlasIED E410 Series Round Torsion Spring Enclosures for 4-Inch Loudspeakers

The AtlasIED E410 Series includes a versatile line of round torsion spring enclosures purpose-built for use with 4-Inch loudspeakers and compatible torsion spring grilles. Constructed from 22-gauge CRS steel and finished with a textured black epoxy, these durable enclosures are engineered for flush-mount ceiling installations in commercial audio environments. All models are equipped with torsion spring receptacles for quick and secure grille mounting.

The series offers multiple variations to suit different installation needs. The standard E410 provides a 1/4 cubic foot (.007m³) volume and is available with or without conduit knockouts. The E410NK version is identical in size but does not include knockouts, making it ideal for sealed applications. The E410-11 offers a high-volume, 1/2 cubic foot (.014m³) enclosure designed to enhance low-frequency response, and includes high-density fiberglass fill for superior acoustic damping—also without knockouts.

Ideal for contractors and integrators, the E410 Series supports multiple AtlasIED baffle models and ensures seamless compatibility in distributed sound systems where clean aesthetics and reliable performance are a must.
